Application filed Kay 25,

To all whom it may concern:

Be it known that I, HARRY LANDSIEDEL, a citizen oi the United States,residing at Norwood, Hamilton County, and State of Ohio have invented anew and useful Adding Machine, of which the following is aspecification. v

This invention relates to adding machines.

It is well known that adding and calculsting machines have been, and nowere, provided with connections for operation by motor and heveqelso heenprovided with hand levers fol manual operation. To avoid contusion andpreventing unnecessary operation and movement of parts whose operationis not needed it is desirable to prerent operation of the hand leverwhen it machine is operated by motor. On the other hand, when a machineis being operated by hand, it is desirable to prevent operation thereofby the motor.-

My present invention has special reference to mechenismfor obtainingthese resuits, end an object of the invention is to provide improved andeilective means for preventing movement of the hand-lever when themachine is operatively connected with the motor and to prevent operationof the motor control connections when the machine is adjusted foroperation by the bend lever.

Another object of the invention is to provide means for disabling thefull-stroke derice when the machine is operatively eonnectcd with themotor end for enabling the inlhstiolate device to function when themachine is placed under control of the hand lever end the motorcontrolling connections are disabled There are other objects andedvsntegeons re iilts to he obtained all of which will. sp- A eer "from.the tollowing description, refer being made to the drawings in which lshowing the present in mil in is machine of the Dalton the parts in thepositions v n the machine is under conlever and the motor coning; rnection disabled.

Fig. 3 is a plawview of the present invention, showing the positions ofthe parts as in Fig. 1. y

The rock shaft 1 is the usual controlling shaft of the adding machinelVhen the machine is in use the shaft 1 is rocked forward and backward,and such rocking movements may be imported either by hand lever or bymotor operated connections. I

T he hand lever or handle 2 is operatively connected with one end of therock sheft l by a familiar" clutch device whereby the shaft will beturned in it forward direction when the hand lever or handle is drawnforwvnrdly; but which permits the shaft to he parts when the machine isunder turned in a forward direction by the motor while thehendle'reinains stationary. This clutch device is well known and is notshown in detail.

lVhenthe machine is operated by use or" the hand-lever or handle 2, itfull stroke device isneeded so that the shaft 1 must be tnrned forenough at each operation to permit or to cause proper operation of themachine. The full stroke device shown comprises it segmental arm 3,attached to the rock shaft and provided in its outer end with a numberof notches 4 to be engaged hy theend of a swinging detent or abutment 5to prevent reverse movement of the shaft between the ends of any turningmovement thereof in either direction 7 The swinging, detent or abutment5 swings on a support 6, and is connected with e spring 7. When theshaft 1 is turned in a, forward direction, the segmentnl arm 3 swingsthe lower end of the de'tent i'orwardly; The lower end of the detent 5con tinnes to ride upon the notched outer end of the arm 3 until snidarm passes beyond the lower end of the detent. Backward movement of thearm 3, priorto the completion of its forward movement, and until soldarm 3 passes beyond and out of engage ment with the detent 5, will beprevented by engagement of the detent 5 in the notches 4:

After the shaft 1 has completed its forward turning movement and er thearm 3 has passed the detent 5, the shaft may return to its startingposition. During backward turning of the shaft the detent 5 rides uponthe outer end or" the arm 3 and prevents reverse or forward turningmovement of the shalt until the backward turning movement thereof iscompleted.

A lever 8 is pivotally supported by the shaft 1. The rear end of thelever Ft engages behind a stud 9. extending from an arm 10 that is rigidwith the shaft 1. The forward end of the lever d has anantid'rietionroller 11 engaged by a motor driven arm or lever 12.Baekward movement of the lever arm 12 will turn the shaft 1 in a torwarddireetion to the full extent required. but return movement of the lever1; permits the shaft 1 to be returned to its starting point in the usualmanner. The leve arm .12 is operated by the usual eonneetions from amotor 1 3. The motor 13 is of the usual constantly running type. and theeonnee- 'tions tor operating the lever 12 from the motorare ot' thefamiliar arrangement. leaving the lever 12 normally (lisetuiiittttd fromsaid eonneetions so that said lever is onl operated by the motor undereont'rol o'l manipulated deviees provided tor that pun pose.

The eonneetions "for operating the lever 12 from the motor are enelosedwithin a easing H and may be ot the type diselosed in my prior PatentsNo, Leoaass. dated Dee. 2o. 1916. and No. LQTOfs'l-ii. dated July .3.W18. For present purposes it. is Nillilt'ltlli to mention thattheoperation of the lever 1:2 by the motor eonneetions that are housedwithin the easing 14 is under eontrol of a movable part 15. in theembodiment oi' the invention shown. the parts 15 is in the form of anarm or lever to whieh one end of a link '16 is (FOI'HKPtGLl. The forwardend of the link 16 is eonneeted with an arm 17. seeured to a roek shaft18 so that. a rot-king: movement imparted to the shaft in will engageand release the eonneetions within the eas in; H- by which the lever 12is operated.

A bar it) is supportml upon arms 20. altaehed to a shat; 2 The bar 1!)ronstitntes a key for eontrolling the motor eonneetions and, as shown.is eonveniently supported near the keyboard ot' the maehine. lressureupon the bar It) will turn the shalt it in a ,torward direetion. A lever22 on the shaft Qt extends over an arm 23 on the shaft in. By theseeonneetions the shaft 1h is turned to actuate the link '16 as required.to en {Iago and to lisengage the eonneetiions within the easing 1.4;.that operate the lever 12.

My invention eontprises deviees for preventing operation of the handlever or handle and for disabling the full stroke deviee when it isintended to operate the maehine with the motor: and my invention alsoeomprises means tor preventing operation of the lever l2 by preventingoperation ol the devices for engaging and releasing the operatingeonneetions lor said lover, when it, is intended toeperate the maehineby hand instead of by motor.

In the position of the parts shown in Fig. 1. the maehine is adjustedtor operation by hand and the motor eontrol eonueetions are lt)t'l\"\(lagainst operation. An arm 24 attaehed to the shaft 21 extends upwardly.A detent deviee 2 is pivoted upon support 126 and is provided with ashoulder 12? whieli. in the depressed or lowered position of the detentdevice shown in Fig. l. onstitutes an abutment tor the arm zit. so as toprevent operation Of the motor eontrolling key l9. llowever. it thedetent dwiee -35 be raised to the position shown in rigg'. :2. theshoulder 2T is out ol the way of th' arm 2i. leaving themotor eontroleouneetions operative by the key 19. A spring 3 l avinp; one end at--taehed to the forward end ot the detent deviee 25 and its opposite endattaehed to a stationary part of the maehine. eonstitutes an aetuatortor the detent deviee to raise the shoulder 27 thereof above the arm:24.

A slide :29 is operative on supports it eX- tent of movement of theslide being-limited to the length of the slots Kl through \vhieh thesupports 30 extend. .a projeetion 32 on the slide. supports a roll 33.riding upon the upper edge ot the detent deviee 2.3. In the torwardposition of the slide 25 the roll 3%. latehes within a noteh 34- in thedetent device and holds the deteut in the depressed position shown inFig. l. in whieh the shoulder 2T eonstitutes an abutment tor the arm 24.in the rear position of the slide :29 the roll 33 latehes within a noteh3.: in the de tent deviee 25. and permits the springis to raise theshoulder 52? above and out ol' the way of the arm 24. A tinger pieee orknob 36 on the slidine plate 29 extends through a slot in the maehineease and (our-til utes means for moving the sliding: plate from neposition to another.

The devices for preventing: the land lever or handle 2 are also undereontrol of the plate 29. in the Forward position ofthe sliding plate129. the motor is disa led and the maehine is plaeed under eontrol otthe hand lever or handle. While, in the rear position of the slidingplate 3%) the hand lever or handle 2 is loeked against operation and themaehine is placed under eontrol of the motor.

A link 37 has its forward end pivotally eonneeted with the sliding plate29. Said link is provided with a slot 38. receiving: a supporting pin35). permitting sliding movements of the link. The rear portion of thelink 3? eomprises -a eam part 40 operating? under a pin or roll 4-1.earried on the upper end ol a lever 42. Rearward movement of the linkit? will operate the lever -12 to move the lower end thereof forwardlyto the position shown in Fig. 2: while forward movement of the link it?permits the lower end of the lever 42 to swing rearward y to theposition shown in Fig. l.
